A partition plate is provided at a substantially central portion in the front-rear direction of a fuel tank. The first tank chamber and the second tank chamber are separated from each other in a flowable manner, and the lower tank chamber is connected to the first tank chamber and the second tank chamber by a flow passage. A fuel supply pipe to the engine is provided in the first tank chamber in front of the vehicle, and a plug for opening and closing the outlet is attached to the outlet of the flow passage according to the amount of fuel in the first tank chamber.

It will flow into the 1st tank chamber, but when the fuel level is increased to a certain extent and the fuel level rises, the amount of fuel in the 1st tank chamber will raise and lower the float, and in conjunction with that, the plug will close the pipe outlet, and the fuel will The fuel no longer flows into the first tank chamber, and fuel is stored only in the second tank chamber behind the vehicle body. When the level of the fuel in the second tank reaches the level above the partition plate, the fuel flows again from above through the portion of the partition plate that can be circulated, and the fuel tank volume does not change.

As the operation is performed and the fuel is consumed, first, the fuel in the first tank chamber in front of the vehicle decreases, and the center of gravity of the fuel moves to the rear of the vehicle body, so that the change in the stability of the vehicle due to fuel consumption is reduced. That is, the stability ratio performance is improved without changing the vehicle while keeping the specification size of the standard type vehicle. When the vehicle suddenly starts or brakes suddenly, the partition plate suppresses the movement of the fuel, which also has the effect of preventing the fuel from spilling out from the fuel inlet.

To the outlet of the flow passage 5 connecting the first tank chamber 3 and the second tank chamber 4 on both sides,
A plug 7 that opens and closes the outlet is attached, and this plug 7 is linked to a floating that rises and falls according to the amount of fuel in the first tank chamber 3, and the amount of fuel in the first tank chamber 3 reaches a predetermined amount. The opening and closing of the flow passage 5 is performed in conjunction with the float 8 at the position where the float 8 is located.

５を開放するようになっている。In FIG. 1, a plug 7 for opening and closing an outlet provided at an outlet of a flow passage 5 connecting the first tank chamber 3 and the second tank chamber 4 on both sides has a float 8 with a fulcrum 9 as an axis. Although the swinging passage opening / closing mechanism is shown as the first embodiment, various other structures can be adopted. 2, 3, and 4
In the cross-sectional side views of the respective fuel tanks, those that can be considered as opening and closing mechanisms of the flow passages are respectively described in the second embodiment,
This is shown as a third embodiment and a fourth embodiment. That is, in the second embodiment shown in FIG.
When the liquid level drops due to a decrease in the liquid level, the wire fixed to the float 8 pulls up the plug 7 via the pulley to open the flow passage 5. In the third embodiment shown in FIG. 3, the liquid level sensor senses a drop in the liquid level, sends an electric signal, electrically activates the solenoid, and connects the plug 7 with a wire.
And the flow passage 5 is opened. In the fourth embodiment shown in FIG. 4, when the spherical float 8 falls due to a decrease in the liquid level, the flow passage 5 which has been closed by the buoyancy is opened.

ていくので、容量としては変わらない。Returning to FIG. 1, when fuel is injected into the fuel tank 1 from the charging port 6, the fuel first enters the second tank chamber 4 on the right side of the partition plate 2, and passes through the flow passage 5 provided below, and the fuel tank 1 on the left side. The fuel flows into the first tank chamber 3, but when the fuel level is increased by storing the fuel to a predetermined amount in the first tank chamber 3, the float 8 rises, and the stopper 7 moves the outlet of the flow passage 5. As a result, the fuel stops flowing into the first tank chamber 3 on the left side, and the fuel is stored only in the second tank chamber 4 located on the right side and behind the vehicle body. When the fuel level in the second tank chamber 4 on the right reaches above the partition plate 2, the fuel is supplied to the partition plate 2.
Since the gas flows again from above into the first tank chamber 3 on the left side beyond the portion which is open for circulation, and fills the fuel tank 1, the capacity does not change.

る。Therefore, as the work is performed and the fuel is consumed after the fuel in the fuel tank 1 is full, the fuel in the first tank chamber 3 in front of the vehicle first decreases, and the center of gravity of the fuel moves to the rear of the vehicle body. To improve the stability ratio performance of the vehicle. That is, the stability ratio performance can be improved without changing the vehicle while keeping the specification size of the standard type vehicle.

The vehicle is also equipped with a hydraulic oil tank in addition thereto, and it is possible to apply to that. In this case, it is necessary to determine the opening size of the flow passage connecting the tank chambers before and after the partition plate so as to follow the maximum oil amount during operation. In the present embodiment, the tank chamber is divided into two by the partition plate. However, the number of divisions can be further increased to improve the stability ratio performance of the vehicle.
